"They refused to meet with us, so it's hard to have a substantial discussion when they refuse to meet with you," said Walsh.

When asked if Wynn officials were being fair, Walsh said "Absolutely not."

Revere Mayor Dan Rizzo said in a statement that he was troubled by the commission's continued insistence that deals in place for the Wynn casino in Everett are sound.

"We still don't understand now the MGC could bless a process that goes against every principle it has espoused about integrity and is inconsistent with how the matter would be treated in virtually every other jurisdiction with gaming," said Rizzo in a statement.

Mohegan Sun officials said they look forward to working with the city to hammer out an agreement.

"We remain committed to continuing the productive discussions we've had with the City of Boston, and to reaching a comprehensive surrounding community agreement, as we have with eight other neighboring communities. We also look forward to continuing to work cooperatively with the Gaming Commission and demonstrating that Mohegan Sun is the best choice for Massachusetts," said Mohegan Sun CEO Mitchell Etess in a statement.

Wynn officials issued similar comments after the commission's ruling.

"We are pleased with the outcome of the Gaming Commission meeting and their preliminary decision of Surrounding Community status for the City of Boston. We look forward to concluding a Surrounding Community Agreement with the city soon," said Wynn Senior Vice President Michael Weaver in an emailed statement.
